SIG SAUER P229 Legion SAO — Description

The SIG SAUER P229 Legion SAO (Single-Action Only) is a premium compact 9mm hammer-fired semi-automatic pistol designed for shooters who prefer the crisp trigger characteristics and manual operation of a single-action platform. Part of SIG Sauer’s Legion Series, the P229 Legion SAO combines the proven P229 platform with enhanced ergonomics, premium finishes, and competition-inspired trigger upgrades.

Unlike the traditional P229 DA/SA configuration, the SAO model features a single-action trigger system with an ambidextrous manual safety, providing a consistent trigger pull for every shot. It includes a SIG Master Shop-inspired flat trigger, X-RAY3 day/night sights, Legion Gray finish, and black G10 grips with a Legion medallion.

The P229 Legion SAO uses an all-metal construction with a stainless steel slide/frame, compact 3.9-inch barrel, and ergonomic Legion enhancements such as an undercut trigger guard, reduced-profile beavertail, and enhanced checkering for improved control.
